Freezing Temperatures and Pool Equipment

Main Content Starts Here

Close your eyes and pretend you’re swimming. When you picture a pool, what do you see? Chances are, your answer includes sunshine, lounge chairs, frosty beverages, and kids splashing around with noodles and toys.

When you imagine a pool, images of freshly-fallen snow or a cup of hot cocoa don’t spring to mind. Families should enjoy pools in hot weather — freezing temperatures and pool equipment don’t mix.

Of course, you don’t want to swim when the temperature dips below the 40s. But will cold temperatures harm your pool? At Pentair, we work to deliver smart, sustainable pool and spa solutions that create magical, wonder-filled moments by your pool, and the peace of mind that you can enjoy your pool for years to come. Read on to learn more about how to help ensure your pool is ready for winter.

How Freezing Temperatures Can Impact Your Pool

What is it about freezing temperatures that spell trouble for your pool? A quick science lesson: when leftover water in a pipe or your pool heater freezes, it expands. Ice can fracture and crack anything from your piping to your pool pumps to your filtration systems.

Here’s how frozen equipment can impact your pool:

  1. Costly Repair

    The financial cost is the most obvious drawback. If frozen temperatures take your pool heater or pump out of commission, replacing or repairing the unit will eat into your budget.

    On top of the monetary hit, it’ll take your pool out of commission during the relatively small window of viability. When it’s time to open your pool for spring or summer, the last thing you will want to do is deal with the headache and expense of replacing equipment. It’s better to take these preventative measures to protect your pool equipment now so you can soak up the sunshine next summer.

  2. Reduction in Energy Efficiency

    Maybe the ice doesn’t leave your pool out to dry. Perhaps a tiny crack forms, but you otherwise escape winter unscathed.

    Over time, small cracks evolve into big problems. As cracks widen, leaks become worse and worse. Your pool pump will have to work harder, making it less efficient. This extra work increases your energy bill and makes your pool less clean.

  3. Shorter Equipment Lifespan

    Proper pool equipment maintenance helps your equipment operate smoothly and efficiently, season after season. Think about your vehicle. You don’t wait years to check and replace motor oil do you? No! That would result in your engine overheating, resulting in serious and expensive repair costs. Treat your pool equipment the same way. Check out our blog on pool heater maintenance.

    Make the most of your investment by learning how to prevent your equipment from degrading in winter.

How to Prepare Your Pool for Colder Winter Temperatures

Proactively protecting your pool from cold winter temps doesn’t have to be rocket science. Follow these quick tips to give yourself some additional peace of mind this winter and protect your pool from winter’s damaging effects.

  1. Winterize Your Pool

    The best way to prevent snow, ice, and wind from taking its toll on your pool is to shut down your pool at the end of the season and follow the steps to “winterize” it, so your pool can hibernate free from harm.

    If this is your first time winterizing a pool, you’re in luck. We compiled an exhaustive 7-step checklist so you can winterize an inground or above ground pool.

  2. Switch Up Your Equipment

    If your pool equipment is already on the fritz, don’t put the problem off. Not only will you thank yourself come spring when you’re ready to dive into pool season, but you will lessen the chance for further equipment damage. It’s better to upgrade or replace pool equipment to reduce susceptibility to damage. ETi® 400 High Efficiency Heaters from Pentair have titanium heat exchangers to make them resilient against extreme temperatures and corrosion from unbalanced pH.

    Plus, IntelliConnect® Control and Monitoring System controls up to five pool devices and offers freeze protection functionality. All you have to do as a user is slide the "Freeze Protection Mode" toggle within the Pentair Home app. If the outdoor temperature drops below the designated temp within the app, your IntelliConnect can automatically turn on your pump to a preset speed to deliver added peace of mind. A stable wireless connection is required for proper synching freeze protection, as IntelliConnect uses data from the internet-based AccuWeather® weather service and updates hourly.*

Leave Freezing Weather to a Professional

Of course, winterizing a pool isn’t as simple as flipping a switch. Many of the steps require specialized gear, chemicals, and expertise. If you’re worried you may unknowingly damage your pool in the process of winterizing, leave it to the professionals!

Find a local pool professional that can safeguard your pool against seasonal freezing temperatures. Schedule an appointment so you can focus on what’s important: figuring out what new hobby to take up as you wait for the next pool season.
